If you’re thinking about getting dental implants, you’re in good company. Dentists have placed more than 3 million of these popular devices since their introduction in the early 1980s.
But if you have multiple missing teeth, you might think the cost of all those individual implants could put them out of your league. Yes, replacing multiple teeth with individual implants can be quite expensive—but implant technology isn’t limited to one tooth at a time. A few well-placed implants can impart their proven durability and stability to other types of restorations.
For example, we can incorporate implants into a bridge for a series of missing teeth. Conventional bridges are normally fixed in place by altering and then crowning natural teeth on each side of the missing teeth gap with a fixed row of prosthetic (false) teeth in the middle to fill it. Instead, two implants placed at the ends of the gap can support the bridge rather than natural teeth. This not only provides greater stability for the bridge, it also avoids permanent altering the natural teeth that would have been used.
Implants can also support a fixed bridge to restore complete tooth loss on a jaw. The new bridge is attached to a few strategically placed implants along the jaw line to equally distribute biting forces. This can result in a strong hold with excellent durability.
We can also use implants to improve traditional dentures. Dentures normally rest directly on the gums’ bony ridges, depending on a snug fit for stability. But bone loss, a natural consequence of missing teeth, can still occur while wearing dentures, which may in fact accelerate the rate of loss due to the appliance’s constant pressure and friction against the gums.
Instead, just a few implants placed along the jaw can, with attachments built into the denture, hold it securely in place. This not only decreases the pressure on the gums, but the natural bone growth that occurs around the implant may even deter bone loss.
Depending on your situation, there could be a viable restoration solution involving implants. Visit our office for a complete examination and evaluation to see if implants could help change your smile forever.

With their durability, versatility and life-likeness, there’s no doubt dental implants have revolutionized teeth replacement. If you’re considering dental implants, however, there are some issues that could impact how and when you receive implants, or if you should consider another type of restoration.
Cost. Dental implants are initially more expensive than other tooth restorations, especially for multiple tooth replacement. However, be sure you consider the projected cost over the long-term, not just installation costs. Because of their durability, implants can last decades with little maintenance cost. In the long run, you may actually pay more for dental care with other types of restorations.
Bone health. Dental implants depend on a certain amount of bone to properly situate them for the best crown placement. If you’ve experienced extensive bone loss, however, there may not be enough to support the implant. This can often be overcome with grafting — immediately after extraction, at the time of implantation or a few months before implantation — to encourage bone growth. In some cases, though, bone loss may be so extensive you may need to consider an alternative restoration.
Gum Health. While implants themselves are impervious to infection, they’re supported by gum and bone tissues that can be affected. Infected tissues around an implant could eventually detach and lead to implant failure. If you have periodontal (gum) disease, we must first bring it under control and render your gums infection-free before installing implants. It’s also important to maintain effective oral hygiene and regular dental cleanings and checkups for optimum implant health.
Complications from osteoporosis. People with osteoporosis — in which the bones lose bone density and are more prone to fracture — are often treated with drugs known as bisphosphonates. In less than 1% of cases of long-term use, a patient may develop osteonecrosis in which the bone in the jaw may lose its vitality and die. As with bone loss, this condition could make implant placement difficult or impractical. Most dentists recommend stopping treatment of bisphosphonates for about three months before implant surgery.
If you have any of these issues or other complications with your oral health, be sure to discuss those with us before considering dental implants. With proper planning and care, most of these difficulties can be overcome for a successful outcome.

You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.

Dental implants are considered today’s premier method for restoring missing teeth. Obtaining an implant, though, is often a long process and the implants themselves must be surgically placed within the jaw bone. Nothing to worry about, though: implant surgery is a minor to moderate procedure akin to a surgical tooth extraction.
Still like any surgery, this procedure does involve cutting into the soft tissues of the gums and could allow oral bacteria to enter the bloodstream. While most bacteria in the mouth are harmless (and even beneficial) a few strains can cause disease. For some people, especially those with certain heart conditions or joint replacements, this could potentially cause serious issues in other parts of their body that might be highly susceptible to infection.
To guard against this, it’s been a long-standing practice in dentistry to prescribe antibiotics to certain high risk patients before a procedure. Although this departs from the normal use of antibiotics for already occurring infections, due to the circumstances this has been deemed an acceptable measure to prevent disease.
In the past, the categories of patients for which preventive antibiotics were appropriate had been more extensive. In recent years, though, both the American Dental Association and the American Heart Association have adjusted their recommendations. Today, your dental provider may recommend antibiotic pre-treatment if you have a prosthetic (artificial) heart valve, a history of infective endocarditis (inflammation of the inner linings of the heart), a heart transplant or certain congenital heart conditions.
While physicians may still recommend premedication with antibiotics for patients with joint replacements, it’s not as blanket a standard as it might once have been. It’s now only recommended for certain cases, such as patients who’ve received a prosthetic joint within the last two years.
There’s still an ongoing debate about the effectiveness of antibiotic pre-medication. However, there’s evidence medicating before procedures with antibiotics can be beneficial in avoiding infection. If you fall into one of the categories just mentioned or are concerned about infection, feel free to discuss with your dentist if using antibiotics before your implant surgery is wise move for you.

Accidents happen, especially to teenagers involved with sports or similar activities. In an instant they can lose one or more teeth and permanently alter their smile.
Fortunately we can restore a teenager’s lost teeth, but often not immediately as a permanent restoration with a dental implant requires maturity of their jaw structure. Our focus then turns to the age of the patient and the condition of the underlying bone. A future dental implant, your best choice for tooth replacement, depends on bone for support, but also the age of the patient as it relates to jaw development.
There are a couple of ways an accidental tooth loss can harm supporting bone: first and foremost, the impact of the accident itself can damage the bony socket. To find out for sure we may need to perform a cone beam scan, a type of x-ray that allows us to view the area three-dimensionally. If we do find damage, we can attempt to repair the socket through bone grafting.
Bone can also suffer from the long-term absence of a tooth. Bone has a growth cycle in which older cells dissolve and new ones form to take their place. The force generated by teeth when we eat or chew helps stimulate this growth. Without stimulation, as with a missing tooth, the bone may not grow at a healthy rate. In time, it could lose some of its volume and density and not be able to support an implant.
Installing an implant right after tooth loss could help avoid this situation. Bone has a natural affinity with the titanium post imbedded in the jaw and will naturally grow and adhere to it. But we can’t place an implant with a teenager. This is because the jaw is still developing so an implant would gradually become misaligned as the jaw grows. It’s best to install an implant later after full jaw development in early adulthood.
Today, we can place a bone graft in the empty socket right after tooth loss. The graft serves as a scaffold for bone cells to grow on and will help keep the bone volume at a healthy level until we can install an implant.
Timing is everything in restoring a teenager’s accidental tooth loss. But with coordination and care for the supporting bone, a teenager can eventually enter their adult years with their smile intact.
